Hi All, I got Portal 2 for my birthday a few months ago, but because I was so busy planning a wedding and stuff, I didn't even have time to take the shrinkwrap off. I finally unpacked it a few days ago, and I got an error w/ my CD key. I see that this is well - documented, and it happens a lot. I opened a ticket w/ Valve support, and they said I needed a gift receipt. I don't even know which relative got it for me, let alone which store they bought it at. I think Valve is going to "win" on this one. I really would rather play it on my rMBP than on my PS3. If I just re-buy Portal 2 on Steam, can I still link my PSN account to the game? Or is it a special version of Portal 2 that I need to get? Thanks!
